The locking device ofthe present invenT tion is designed for yuse inconnection with spare tire and spare rim carriers, such as form a partof the standard equipment of motor vehicles. As shown in Figures 1y and2, the locking device may be applied direct-ly l.

to the spa-re tire carrier without' necessitating any change oralteration in the standard spare tire carrying equipment. The spare tirecarrier is represented generally at 1,

and aspare rim 2, with a spare tire 3 thereon are shown mounted on thecarrier. A threaded bolt or projection 4, havinga flattened head 5,projects from the carrier for cooperation with means `for retaining thespare tire and rim upon the carrier., The

bolt 4 is rigidly securedl to the carrier by means of Vrivets 6, whichpass through the flattened head 5, the'bolt thus serving asa fixedmember to'which the locking device is adapted to be applied.V Thearrangement thus far described constitutes a part ofl a typical yexampleof the standard equipment with which motor vehicles are generallyprovided. A fiat band 7 formedfof hardened spring steel bent tok conformto the 'Y shape of the carrier and tire, and having a straight inwardlyprojecting'en'd part 8, is adapted to be applied tothe carrier, with thelthreaded bolt 4 passing through an', elongated opening 9 formed in thestraight portion 8; At the opposite end of this band 7 there is formed ahook 10. A second curved band 11 cooperates with band 7 Vand togetherthey form `a tire and nrim encircling member. This band 11 has a hook`12 formed at one end and straight portions V14 and 15 formed adjacentits opposite end,

The hooks 10 and 12 are connected by link'13 in lsuch a way. as to 'forma hinge.

The straight end portion 14 of the band 11"` has anlelongatedperforation 16,. through which .the threaded boltf4 passeswhen' the band 11 is swung up into tire encircling position.

A` cylindrical memberl' serves as a housingfor theY lock mechanism, andvhas. its wallsslotted or recessed atene end at points whichare'diametrically opposite, as indifcated at '17. The straight portion14 of the band 11y is arranged inV these slots 17 and retained thereinby ,welding or any other desirable means. vnThe'end portion 15 of theband 11 is bent'down so las to lie along the peripheral surface of thehousing 17, and to conform tothe curvature thereof. `Thus it will beseen that the housing 17 and the -ba-nd 11 are rigidly secured togetherWith thefstraight portion 14 of the band11 forniing the bottom of thehousing. `While it is not iiecessaiy for the successful operation of thedevice 'that housing117 and band 11 beV rigidly secured together,however,v for convenience in using the device, preferthis construction.n p *Y e The Vlecl; mechanism, designated generally at 18,isfi'otatabl'y mounted Within theA ,housing 17. .The lock vinechf/inismlcomprises an operating member 19, a cylindrical nut or retaining member20,v and a cup-A shaped lcollar 21 inV which the` retaining member 2 O.is seated, and Which engages` a reduced cylindrical 'portion 22 offtheoperating member; 19. For the inirposel of securing the housing 17 andcollar 21 together in relativelyv rotatable arrangement, the outerperiphery ofthe collar 21 has formed therein an annular Agroove V, vandin. theV inner periphery of" the housing 17 there isformed vannulargroove 24 which registers with the groove 25. A ring shapedspri-ngmember 23 is compressed into the annular groove 25 as the unit 18l isslidl into the housing .17, and when, groove 25 registers lwith thevgroove 24the ring eXpandsso as to then engage bothl grooves andthus secure the partstogether.' A similar locking spring, designated 26,v isprovided between' the operating memberA 19 and the. collar 21, to securethese members together inv rela,- ivelyY rotatable arrai'igemeiit.` The.retaining member. 20', Vwhich is, Yin effect, a nut, has an opening '27therethrough,.which isl threaded to engage with the threaded bolt fl,rlheretaining member 20 is formed with an enlarged cylindrical end 28,which is yre-V tainedivithin the collar 21 by means of the -inturnedflange 29 formed on the end of f thecollar. In the face of the enlarged'portion 28 of the retaining member there is provided a plurality, ofrecesses y3,0 arranged concentrically about the aXis of the retaining.;member. The operating member is Vprovided with a projection on onej end,.which assumes the shape of afhexagon nut 31; Fromrtheopposite end ofthe operating Y member slidable bolts= 32 project, Thelbolts are adaptedto yslide in recesses 33,'in-1tne innervgends of which coil springs .34:yare 4 housed for engagement with the inner ends 'of thebolts.v i Thesliding bolts r32 are connected by means .of a pin 35, so that the boltswill operate in unison.. Slots 86 areprof videdto accommodate .thevpassage of' connecting pin 35, as boltsv32' slide in and-out. Theslidable bolts 32 are so. spaced that they will engage in two oftherecesses 30, ofthe retainingimember 20, ywhich are vdiai'netricallyopposite each other.. l l v 1 A cylinder lock 37 is, rotatably-mountedin the operatingmeinberfl), with' itsnainlsfin` draWal of cylinder' loch3Y tersectiiig the axis of the ol'ierating member.v 'f

On the inner end of the cylinder lool( is se l cured a plate 38, Whichrevents the with- Tliis plate carries an cccentrically mount# frommember 19.

ed pin 39 which engages connecting pin 3 5 as Athe cylinder `lool; 37is'rotated by means of keyLO, and thus retracts bolts 32 y against theaction of coil springs 34. lWhen thebolts are in theretractedposition,tlie` springs 34 .are Vcompressed andl the paivls 37 oflcylinder lock 37 are in alignment with one of the slots 3S yformed inmember l19. Upon 1 withdrawing the key l0Y the paWls 37 .are projectedradially outwardly into one of the slots 3S loclringtlie cylinder lockVagainst rotation While the lrey is Withdrawn. l v

It will new be readily apparent lthatzby insertion ofthel key 40, thepawls 37 will be retracted, thus freeing cylinder .lock 37 and eccentricpin 39 for rotation, which will permit compressed springs 34- tofoivce'the4 sliding bolts 32 outwardlyto engage in the Another foimwhichthe locking meoliay nism of this invention may assai-ne is shown inFiguresr G, 7 and 8; In this arranggel ment a retaining member isprovided with a lieziagon shaped head l51, .wliichis adapted to beengaged by a slidable. henagon shaped sleeve or sochet52. The retainingmember 50, havingan opening centrally rtlioretlirough, Which is threadedfor engagcment withV threaded bolt 4, isretained Withinthe cup-shapedcollarl by means ofthe inturiied flange 54. 0n the en'd of sleeveinein'berl52 opposite the hexagon shaped socketwthere are formeddiametrically opposite lugsA 55, Which slidably'en-v gage in slotsA 53of member 6.0., il pin 56 connects ,lugs and has an 'end lixedly mountedin each lug. The free LYends `of the lugs 55 terininatein reducedprojections'57,

ii y

Which serve as centering'ineans for the eoinpression springs 58 whichare seated in rie-i Rotatably mounted in member GVO is acyl;

inder lock G1, positioned so thatv its-axis will intersect the axis ofmember 60'. On the inner end of cylinder lock 61 isi carried a Vplate62, having an eccentric lug 63 formed integral therewith.v rihev yplate62 prevents ythe.,cylinder)loch 6,1 from being A.

Withdrawn from` the member 60'. The lug 63 is formed by making theplatee62fvvith a peripheral extension, andy then bending" over. thisextensioncto a position lati-ight t angles With the plane; oftl'ic-i-plate,.` This" projection G3 is curved so that the curvedsurface (il will be in rolling engagement with the pin 5G with which lug63 engages. Thus it will be seen that by manipulation of the key 10, thecylinder lock 61 can be rotated to bring eccentric lug 63 intoengagement with pin 56, to thereby cause the sleeve to movelongtiudinally along its axis to compress springs 58 and to disengagethe hexagon head 51 of the retaining member 50. The inner end of member60 is formed with a reduced cylindrical por# tion 66, in whichaperipheral groove v67 is formed. On the opposite end of member 60 thereis provided a hexagon shaped extension 68. A cover member 69 having ahexagon shaped recess 70 is adapted to lit over and encompass member GO.rIhis cover member 69 is provided with a flange 71, which When spun orpressed down against the shoulder 72 of the member GO serves to maintainthe cover 69 in place over member GO. A peripheral groove 73 is rolledor otherwise formed in the cylindrical portion ot the cup-shaped collar54. When this peripheral groove is rolled into the member it causes aprojection 7-i to be termed on the inner periphery of the collar 54:,and this projection 74 engages in the annular groove 67 formed in themember 60. The annular projection 74C and the annular groove 67 thusserve to retain the parts of the locking mechanism in assembledposition, as shown in Figures 7 and S. Annuler groove 7 2l furtherserves to coo]' erate with a. peripheral groove similar to groove 24,shown in Fig. 1, to retain the locking mechanism Within the housingincinbcr 17 in relatively rotatable arrangement.

The operation ot the device is as follows:

Spare rim 2 with tire 3 mounted thereon placed in position on carrier 1,and the locking novice is swung up With hook 12 and link 123 serving asa hinging point, thus bringing the threaded opening 27 of retainingmember 2O into. alignment vWith threaded bolt 4. By applying a Wrench orsimilar tool to the hexagon headed extension 31the operating member 19may be rotated Within the housing 17 and rotation Will thereby beimparted toretaining member 20 by means of the sliding bolts 32 engagedin the recess 8O thereof. Upon rotation of retaining member 20, thethreaded opening 27 thereof Will engage .With the threads of bolt 4 anddraw the locking device into position with straight portion 14C of band11 bearing against straight portion S of band-7, and with housing 17bearing against the spare rim 2. l When the operating member has thusvbeen turned sulliciently to tighten the member 2O and force theflattened portion 14 of the band 11 against the flat portion 8 of theband 7, key el() is turned to thereby impart rotation to the cylinderlock 37 and the eccenvconnecting pin 35 and retract sliding bolts 32from the recesses 30 oi' the retaining member 2O against the action or"the coil springs Se. lhen the sliding bolts are thus retracted theoperating member 19' is free to rotate within the housing 17 Withoutimparting rotationv to the retainingv ymember 20. When the key 1sWithdrawn the device will then be in locked position with housing 17bearing against the rim 2 and bands 7 and 11 encircling the tire andrim. y

The operation of the locking unit shown in Figs. 6, 7 and 8 isessentially the same as the operation of the unit shovvn in Fig. 2 and,therefore, need not be repeated. In connection with both forms ot thedevice it is to be noted that by providing housing 17 with slots 17 inthe Walls at one end ot the housing, the flat portions 14 and 8 of theban/ls 11 and 7, respectively, Will both lie Within these slots 17 whenthe parts are in locked position. The portions of the Wall of 'thecylindrical housing 17 which thus overlap the portions 14 and 8 of theencircling bands prevent the insertion of a hack saw blade or other toolbetween the flat portions 8 and 14, :tor the purpose of severing Ythebolt 4:. Furthermore, Ythe device as shown does not present any portionby which it can be grasped securely enough to shear or twist the bolt 4from the carrier.

Having thus described my invention, I claim:
